I purchased a certified EGL diamond (G-VVS1) back in 2001 and have lost my EGL certificate since. I called the original jewelry store and they no longer have me on record/files. I called EGL to see if they could obtain the copy but without any of the certificate information they couldn''t help me either. The deal was if I decided to sell the diamond back to the store I would only lose 10% of the orig. purchase price (10k) which means I would get back 9k. I''m wondering if it''s a better deal to just get the diamond certified again and get an appraisal to find out which way is worth more and if I should sell the diamond back to the original store. Does anyone have any suggestions?
